Simple Physics Practice Quiz
Q1. What is the SI unit of force?
Force is measured in Newton.
Q2. Which quantity tells us how fast an object is moving?
Speed tells us how fast an object moves.
Q3. What is the formula for speed?
Speed is calculated by dividing distance by time.
Q4. If an object travels 100 meters in 20 seconds, what is its speed?
Using ##speed = distance / time##, we get ##100 / 20 = 5## m/s.
Q5. What is gravity?
Gravity is an attractive force. On Earth, it pulls objects toward the center of the planet.
Q6. Which instrument is used to measure temperature?
A thermometer is used to measure temperature.
Q7. What happens to the speed of a falling object under gravity if air resistance is ignored?
Without air resistance, gravity causes the falling object to accelerate, so its speed increases.
Q8. Which of these is a source of light?
The Sun produces its own light. The Moon and mirror only reflect light.
Q9. What is energy?
Energy is commonly defined as the ability to do work.
Q10. Which simple machine is used to lift heavy objects more easily by using a wheel and rope?
